To all'whlomitmw'y concern.'

Be it known `that I, INos B. TANNER, 3240 South Michigan Boulevard, Chicago," citizen oftheiUnited States, residingatGhicago, in

I' the county of Cook kandState 'of Illinois,

have invented a certainnew and `useful Im- Jrovementin Tanks, ofwhich the following is `a full, clear, concise,fandexact description.

Myinvention Lrelates'tto tanks and has for its object the provision of 'asubstitute for the bottom portions `of tanks, as` tanks are now constructed, whereby lvariousf objections hitherto obtained may be'ove'rcome.

` "In practicingimyfinvention, the tank body and the tank bottom are formed separately and :are afterwardsVassembled. The tank bottom is formed of concrete instead of the other materials hitherto employed and is of such a shape as to constitute also a tank support. The support or foundation is desirably so formed as further to constitute an outlet for sludge. The body of the tank may be formed of wood, though the inven tion is not to be thus restricted.

In order that the tank body may be effectively assembled with the tank bottom or foundation, such a bottom or foundation is formed with an outer ledge located below the top of the foundation or bottom and the tank body is seated upon this ledge so that a portion of the tank foundation or bottom extends upwardly into the tank body to constitute an elfective liquid seal between the body and bottom.

The concrete bottom is desirably integrally formed with legs at the tank body to be in supporting relation to the tank body and the outer portions of the tank bottom, and the bottom of the tank desirably converges outwardly toward the axis of the tank and there preferably terminates in a downwardly projecting pipe section through which the sludge may be withdrawn and which also desirably constitutes an axial support for the tank.

The invention will be more fully explained in connection with the accompanying drawings showing the preferred embodiment thereof and in which Fig. 1 is a view in elevation, partially in section, of a tank embracing the invention; Fig. 2 is a sectional view on line 2-2 of Fig. 1, with portions broken away; Fig. 3 is an enlarged View of some portions of the structure as they ap and has a 'portion 3 which constitutes the botto-m ofthe tank. `This tank bottom is formed `with-fa fledge 4 at` its periphery, this lledge beinglocatedbelow thetop` 5 -of` the tank bottom, whichbottom Ithus. projects slightly within the tank body and serves to afford a liquid tight joint between the tank bottom and Vtank body, this body being placed upon the ledge 4.

The bottom of the tank desirably tapers downwardly toward the axis of the tank to be of conical form to serve as atapering pocket for the sludge which may settle at the bottom of the tank, this construction being particularly desirable if the tank is employed in water softening equipment. The bottom of the tank terminates, at the axis of the tank, in a piping portion 6 formed of concrete integrally with the balance of the tank bottom and closed by a base wall 7, also formed of concrete and integrally with the balance of the tank bottom to serve as a support at the axis of the tank. A metallic pipe 8A establishes communication between the interior of the piping section 6 and the place where the sludge is to be received, there usually being a valve, not shown, in the pipe 8. The tank bottom and body are further supported by legs 9 formed of concrete integrally with the balance of the tank bottom and located at the perimeter thereofto be in supporting relation to the border portion of the tank bottom and the tank body seated on the tank bottom. The concrete structure may be reinforced by any suitable means such as the iron rods 10.

A treatment chamber 11 is shown within the tank, this treatment chamber initially receiving the water that is to be softened and the chemical which is to soften the water, all as is well understood by those -skilled in the art. This treatment chamber is desirably in the form of an iron pipe which is coaxial with the tank and which rests upon posts 12 projecting upwardly into the tank and located at the central portion ot the tank bottom. These posts 12 are desirably formed of concrete and integrally with the balance of the tank bottom. The softened water passes from the bottom of the treatment chamber 11 through the spaces between the posts 12 and into the space sur- .f rounding the treatment chamber, from which latter space the softened water is withdrawn for use. The sludge is precipitated from the treatment chamber into the concrete pipe portion 6, from which the sludge may be withdrawn through the pipe 8.

It is obvious that changes may be made without departing from the spirit of my invention.

Having thus described my invention I claim as new and desire to secure by Letters Patent the tollowing:-

1. The combination with the body portion of a tank; of a concrete 'foundation upon which said body portion is placed and inclusive of a portion constituting the bottom wall of the tank and downwardly converging toward the aXis of the tank and terminating in a discharge pipe integrally formed therewith, and also formed with supporting legs at and projecting downwardly Jfrom the body portion ot the tank.

2. The combination with the` body portion ot a tank; of a concrete foundation upon which said body portion is placed and inclusive ot a portion constituting the bottom wall of the tank and downwardly converging toward the axis of the tank and terminating in a discharge pipe integrally formed therewith and constituting a support for the tank and also formed with supporting at and projecting downwardly from the body portion of the tank.

3. The combination with the body portion of a tank; of a concrete foundation with which said body portion is assembled and forming thel bottoni wall of the tank and having upwardly extending posts integrally formed therewith and located within the tank; and a treatment chamber within the tank and carried upon said posts.

In witness whereof, I hereunto subscribe my name this 1st day of November A. D.,

INOS B. TANNER.
